Impact of ground-level ozone on tropical forests

Elevated ground-level ozone (O3), a result of human activity, is known to reduce plant productivity but its impact on tropical forests remains unclear. Here for the first-time we measured the O3 susceptibility in a range of ten tropical tree species and use these data to determine how changing O3 exposure has impacted tropical forest productivity and the global carbon cycle., This deposit represents i) data on experimental conditions and results from work investigating the impacts of ozone (O­3) on saplings of ten tropical tree species, ii) how this empirical data was used to parameterize a global land surface model as well as iii) global model outputs for the impacts of O3 on tropical forests and the global carbon cycle and iv) formatted data and R-code needed to replicate all figures within the associated manuscript.
Experimental facility
All empirical work was conducted at the joint University of Exeter (UoE) and James Cook University (JCU) TropOz research facility (www.tropoz.org) located at the James Cook University’s Environmental Research Complex (www.jcu.edu.au/environmental-research-complex) on the Nguma-bada campus in far-north Queensland, Australia. The facility consists of nine independently controlled and monitored Open Top Chambers (OTC) which allows for the examination of plants grown under ambient CO2 and nine different O3 concentrations usi..., , # Data from: Impact of ground-level ozone on tropical forests

## Description of the data and file structure

## Experimental Data

Consists of 13 data files representing a summary of experimental conditions and data produced by a series of experiments using Open Top Chambers to determine the O3 susceptibility of  ten tropical tree species.  

**Experimental conditions:** Ten data files of O3 concentrations and meteorological conditions for the OTC experiments conducted on ten species of tropical tree seedlings listed in Extended Data Table 1 of the manuscript. Each file has the same structure and parameters (see below)

            \"*Cb_merged_data.csv*\" =*Carallia brachiata* ...

地表臭氧（ground-level ozone, O₃）浓度升高由人类活动引发，已知会降低植物生产力，但其对热带森林的影响仍不明朗。本研究首次针对十种热带树种开展臭氧敏感性测定，并利用这些数据解析臭氧暴露变化如何影响热带森林生产力与全球碳循环。
本数据集涵盖：i) 探究臭氧（O₃）对十种热带树木幼株影响的实验条件与结果数据；ii) 利用该实测数据对全球陆面模型（global land surface model）进行参数化的相关过程数据；iii) 臭氧对热带森林及全球碳循环影响的全球模型输出结果；iv) 复现相关论文所有图表所需的格式化数据与R代码。

### 实验设施
所有实测工作均在埃克塞特大学（University of Exeter, UoE）与詹姆斯·库克大学（James Cook University, JCU）共建的TropOz研究平台（www.tropoz.org）开展，该平台坐落于澳大利亚昆士兰州北部远北地区Nguma-bada校区的詹姆斯·库克大学环境研究综合设施（www.jcu.edu.au/environmental-research-complex）内。该设施包含9个独立控制与监测的开顶箱（Open Top Chambers, OTC），可用于研究在背景大气CO₂浓度与9种不同臭氧浓度环境下培育的植物……
